gear 8, this engagement being efiected by means of the bayonet jointaforesaid. The operator then moves the rod 30 carried 1n the handle 25upwardly, thereby elevating rod 14 and detent 18 until the latter isdisengaged from, gear 2, so that said gear is free to be operated byrotation of driving gearS by means of the crank handle 27 on theoperatorfs rod.

The operatinglhandle25 is then disengaged from The device; asdescribed, is particularly effective, not only in respect of thesimplicity of construction and operation thereof, but as a safeguardagainst the tampering with the awning'and 'its' operating device by misschievous persons, as the operating devices per se are locatedout ofreaoh,fexceptfby means of the removable operating handle, the removal ofwhich handle effects the automatic lockingott the" awning roller.
